On top of that, inspections this summer by Cask Marque revealed that a quarter of pubs were serving cask above the recommended temperature of between 11 to 13 ̊C.

James Nicholls, Senior Brand Manager at Sharp's Brewery said: "Doom Bar Extra Chilled is an exciting opportunity for us to respond to changing consumer trends, and appeal to both traditional ale drinkers as well as new audiences."

It will also aim to inject some life into overall cask sales which have dropped 20 per cent over the last five years.
